Biography

The research of Dr. Xuan Liu’s laboratory focuses on developing novel optical imaging and sensing techniques for biomedical applications. One major area of our study is optical coherence tomography (OCT) which provides high resolution cross-sectional images of biological specimen in real-time. OCT has been used to help the diagnosis of various diseases in ophthalmology, cardiology and oncology. Currently, we are developing a manually scanned OCT system with a miniature probe. Moreover, we are also interested in extraction functional information from OCT images to characterize chemical and mechanical properties of biomedical specimens or synthetic biomedical materials.

 Dr. Liu received her B.S . and M.S. degrees from Tsinghua University, Beijing, China. She started to study in the Johns Hopkins University since 2007 and received her Ph.D degree in 2011. Before joining the faculty of Michigan Tech, Dr. Liu worked as post-doctoral fellow in the Johns Hopkins University.
